Abstract
The utility model relates to a novel intrauterine contraceptive device, which comprises a metal wire, a contraceptive copper head and a fixing clip, wherein, the contraceptive copper head is fixed at the middle part or the tail part of the metal wire directly, or the contraceptive copper head is installed on the middle part or the tail part of the metal wire through the fixing clip. Since the utility model adopts a suspended type structure that the metal wire is provided with a contraceptive copper ball, the utility model has the advantages of difficult shedding, high contraception success ratio, small specific surface area, small size, no relative displacement when uterus contracts, no friction, not inflammation and small side effect. Since TiNi memory alloy wire has good biocompatibility and no organization adhesion, the utility model is implanted in or taken out of the uterus without uterus expansion or without large uterus expansion, so the pain is reduced obviously, and the utility model is an ideal novel intrauterine contraceptive device.
Description
This utility model relates to a kind of female contraception intrauterine device, belongs to the improvement of female contraception instrument.
In the prior art, still there is not a kind of ideal female contraception intrauterine device.Present intrauterine device mainly contains O type ring, T type ring etc., because specific surface area is big, the relative displacement that uterine contraction causes makes endometrium be in andfrictional conditions for a long time, easily causes inflammation.Thereby, using present intrauterine device, most women have untoward reaction such as menorrhagia, menstrual period pain; And, need expand the palace when implanting or taking out because the volume of O type ring, T type ring is bigger, the patient is painful.
The purpose of this utility model is intended to overcome deficiency of the prior art, a kind of comparatively ideal intrauterine device is provided, have that volume is little, specific surface area is little, no friction, difficult drop-off, contraception success rate height, side effect be little, need not to expand the palace when implanting or taking out or need not the obvious advantage in big expansion palace.
The purpose of this utility model is achieved in that and has designed a kind of new intrauterine devices care, comprise tinsel, contraception copperhead and fixing card, the contraception copperhead directly is fixed on middle part wiry or afterbody, perhaps is installed in middle part wiry or afterbody by fixing card.
---above-mentioned tinsel is made with the NiTi shape-memory alloy wire usually, also can satisfy human body with medical stainless steel silk or titanium silk or other and implant the tinsel or the macromolecular material silk thread that require and substitute.
---above-mentioned contraception copperhead is usually with medical copper or copper alloy manufacturing.
---above-mentioned contraception copperhead also can reach other metal material manufacturings that contraception requires with other implant into body uterus.
---above-mentioned contraception copperhead also can substitute with the slow releasing capsule that contains contraceptive.
---above-mentioned contraception copperhead can have different geometric shapes, is generally sphere, elliposoidal, annular, heart with holes.
---also can have through hole on the above-mentioned contraception copperhead, tinsel passes through hole, links to each other with tinsel by the fixing card copperhead of will practising contraception.
---above-mentioned contraception copperhead also can directly be fixed on middle part wiry or afterbody, does not need fixing card.
---the said fixing cartoon is used the macromolecular material manufacturing always, as medical plastic, also can use other material substitution.
During clinical use, with the custom-designed apparatus of broadcasting, the part of head wiry is inserted the bottom, uterus, the copperhead of will practising contraception is suspended on intrauterine by tinsel; The contraception copperhead has the afterbody tinsel can being exposed at outside the cervix uteri of buttock line.When needing to take out, clamp the tinsel head with surgical clips and can pull out gently.Because this utility model has adopted the tinsel afterbody to fix the suspended structure of contraception copperhead, difficult drop-off, contraception success rate height, uterine contraction does not have relative displacement, does not have friction, is difficult for inflammation; And specific surface area is little, thereby side effect is little; Because of the biocompatibility that the intrauterine device volume is little and the TiNi memory alloy wire is good, the inorganization adhesion of this utility model, need not to expand the palace or need not big expansion palace when implanting or taking out, pain obviously reduces, and is a kind of comparatively ideal intrauterine device.Good social benefit and economic benefit are arranged.
Concrete structure principle of the present utility model and operation principle are provided by the following examples and accompanying drawing:
The structural representation of the elliposoidal intrauterine device of Fig. 1 this utility model;
The structural representation of the spherical intrauterine device of the fixing card of the nothing of Fig. 2 this utility model;
The structural representation of the annular intrauterine device of Fig. 3 this utility model;
The structural representation of the heart-shaped intrauterine device with holes of Fig. 4 this utility model;
The structural representation of the slow releasing capsule type intrauterine device that contains contraceptive of Fig. 5 this utility model;
The operation principle sketch map of the intrauterine device of Fig. 6 this utility model:
Among the above-mentioned figure, 1 is tinsel, and 2 are the contraception copperhead, and 3 are fixing card, and 4 is through hole, and 5 for containing the slow releasing capsule of contraceptive, and 6 is the intrauterine device of this utility model, and 7 is fundus of uterus, and 8 is tissue.
During enforcement, buying recovery temperature and be 20～35 ℃, diameter is the NiTi shape-memory alloy wire (1) of 0.03～0.38mm, and the typing be heat-treated to straight line, perhaps buying diameter is the medical stainless steel filament (1) of 0.03～0.38mm: by common metal working process carry out the contraception copperhead (2); Carry out fixing card (3) by common plastic processing; Contraception copperhead (2) and fixing card (3) are installed on the middle part of tinsel (1) or afterbody successively, and fixing card (3) the downward landing of copperhead (2) that can prevent to practise contraception can obtain the intrauterine device of this utility model, Fig. 1 and Fig. 3.Perhaps adopt riveted joint or other metal working process method copperhead (2) of will practise contraception directly to be fixed on the middle part or the afterbody of tinsel (1), form fixing intrauterine device, Fig. 2 of blocking of nothing of this utility model.Also can have through hole (4) in contraception copperhead (2), tinsel (1) passes through hole (4), links to each other Fig. 4 by fixing card (3) copperhead (2) of will practising contraception with tinsel (1).Contraception copperhead (2) also can substitute with the slow releasing capsule that contains contraceptive (5), directly is fixed on the tinsel (1) Fig. 5.
During clinical use, insert in the tissue (8) of fundus of uterus (7) with the head of special-purpose delivery device the tinsel (1) of the intrauterine device of this utility model, make contraception copperhead (2) be suspended on intrauterine by tinsel (1), bio-toxicity because of copper ion, kill germ cell or disturb the implantation of germ cell, reach the effect of contraception.When needing to take out, clamp tinsel (1) afterbody with surgical clips and can pull out Fig. 6 gently.
